Joshua 22:10-14

10And when they came to Geliloth1 near the Jordan in the land of Canaan, the Reubenites, the Gadites, and the half-tribe of Manasseh built an imposing altar there by the Jordan.

11Then the Israelites received the report: “Behold, the Reubenites, the Gadites, and the half-tribe of Manasseh have built an altar on the border of the land of Canaan, at Geliloth near the Jordan on the Israelite side.” 12And when they heard this, the whole congregation of Israel assembled at Shiloh to go to war against them.

13The Israelites sent Phinehas son of Eleazar the priest to the land of Gilead, to the Reubenites, the Gadites, and the half-tribe of Manasseh. 14With him they sent ten chiefs—one family leader from each tribe of Israel, each the head of a family among the clans of Israel.
